VISUAL STUDIO CODE AUTOCOMPLETE INSTALL
Next, it’s time to install the boto3 VSCode Plugin, which you can do by navigating here and hitting the “Install” button. get_item ( Key =, ) def main (): dynamodb_fun () if _name_ = "_main_" : main () Import boto3 def dynamodb_fun (): table = boto3. First, we’ll create a working directory with a new virtual environment. The relatively new VSCode extension for boto3 makes using the library simpler than ever. The boto3-stubs module ( Github) can be used to enable Autocomplete. So… what are we going to do about this? Fortunately, some clever and dedicated people have created a solution that is now easy to use. The more significant drawback is that Autocomplete can’t discover these structures because they only exist in a running program - not something static code analysis can help with. That’s usually a one-time penalty because they’re cached in memory. When you first instantiate the clients or resources, there is a performance penalty because the parsing needs to happen, and the data structures must be created.
VISUAL STUDIO CODE AUTOCOMPLETE UPDATE
From a technical perspective, this is pretty cool because you can update the SDK by changing the definition files. The SDK then constructs the methods and classes based on the JSON definition. These documents are only parsed when boto3 or botocore are used, i.e., imported and instantiated somewhere. Here’s an example from the DynamoDB API in the botocore module. The data directory in the boto3 package only contains the definitions for the resource API. You can find the majority in the underlying botocore library.
The reason is that the API methods and data structures are only shipped as JSON documents.
If you look at the Python code installed when you run pip install boto3, you’ll have trouble finding all the API methods you can use. This means it analyzes the code without executing it. Usually, the Autocomplete functionality relies on performing static code analysis on the existing code and the installed dependencies. Today I’m going to show you how easy it has become to enable Autocomplete for boto3 in VSCode.īefore we come to the solution, let’s talk about why native Autocomplete doesn’t work with boto3. One of the less pleasant aspects of working with AWS using Python is the fact that most IDEs aren’t able to natively support Autocomplete or IntelliSense for the AWS SDK for Python (boto3) because of the way boto3 is implemented.
